Stork OTC vs Natural Intercourse Comparison

“Three times the sperm value is quite significant for so many couples, especially with the growth of male factor infertility. Understanding the growing value of semen for successful conception, and having a technology like The Stork® OTC that can deliver more sperm to the cervix than natural intercourse, this at-home conception may greatly impact many couples on their path to building a family. The Stork OTC makes sense.”
